Product details
Overview
DS1100LU-50+T&R from Maxim Integrated is a 3.3V, 5-tap silicon delay line with nominal delays of 10ns (TAP 1), 20ns (TAP 2), 30ns (TAP 3), 40ns (TAP 4), and 50ns (TAP 5), operating over -40°C to +85°C, driving up to 10 LS-TTL loads per tap, and housed in an 8-pin µMAX package for high-density PCB layouts.
For engineers reviewing the DS1100LU-50+T&R datasheet, DS1100LU-50+T&R pinout, DS1100LU-50+T&R application, or DS1100LU-50+T&R equivalent, key selection criteria include tap delay precision (±4ns over full temperature range for ≤40ns delays), leading/trailing edge matching, 3.3V CMOS/TTL compatibility, and µMAX footprint constraints in timing-critical digital systems.
Technical Context
The DS1100LU-50+T&R implements a monolithic all-silicon delay architecture-no hybrid or RC-based elements-with five fixed, equally spaced delay taps derived from a single input signal. Each tap reproduces both logic edges with matched propagation characteristics, eliminating skew-induced timing errors in synchronous sampling paths.
It operates exclusively from a 3.0V–3.6V supply, delivers outputs compatible with TTL and CMOS logic families, and maintains delay stability across voltage and temperature via unidirectional drift behavior-i.e., all taps slow or speed together under varying conditions, preserving inter-tap spacing integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0V to 3.6V - ensures compatibility with modern 3.3V digital systems without level-shifting. |
| TAP 5 Delay | 50ns nominal - defines maximum fixed latency for time-stamping, pulse-width modulation, or clock deskew. |
| Delay Tolerance (≤40ns) | ±4ns over -40°C to +85°C - guarantees deterministic timing margin in industrial environments. |
| Output Drive | 8mA sink / -1mA source - supports direct interface to 10× 74LS loads without buffering. |
| Input Pulse Width | ≥20ns - sets minimum usable signal duration for reliable tap activation. |
| Power-Up Time | 200μs - defines system initialization delay before stable delay operation begins. |
| Operating Temp | -40°C to +85°C - qualifies for extended-temperature industrial and automotive under-hood applications. |
Pinout & Package
DS1100LU-50+T&R is packaged in an 8-pin µMAX (U8+1) surface-mount outline, measuring 3mm × 3mm × 0.8mm, with exposed pad for thermal enhancement and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Single-ended logic input accepting TTL/CMOS-compatible signals; referenced to VCC/GND. |
| 2 | TAP 2 | Second delay output (20ns); electrically identical to other taps, capable of driving 10 LS-TTL loads. |
| 3 | TAP 4 | Fourth delay output (40ns); matches TAP 2/TAP 1/TAP 3/TAP 5 in edge fidelity and load drive. |
| 4 | GND | Digital ground reference; must be low-impedance and decoupled near VCC pin. |
| 5 | TAP 5 | Fifth and longest delay output (50ns); same rise/fall time (2.0–2.5ns) as all taps. |
| 6 | TAP 3 | Third delay output (30ns); delay tolerance tracks TAP 1–TAP 5 unidirectionally with temp/voltage. |
| 7 | TAP 1 | First delay output (10ns); shortest fixed latency path; ±4ns accuracy over full temperature range. |
| 8 | VCC | +3.3V supply input; requires local 0.1μF ceramic decoupling capacitor adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| All-silicon delay core | Eliminates aging, humidity sensitivity, and parameter drift inherent in hybrid or RC-based delay lines. |
| Matched leading/trailing edge delay | Ensures symmetrical pulse width preservation across all five taps-critical for clock recovery and data eye alignment. |
| Five equally spaced taps | Provides discrete, calibrated latency steps (10/20/30/40/50ns) without interpolation or external circuitry. |
| µMAX package (3mm × 3mm) | Reduces PCB area by >50% vs. SO-8 while maintaining thermal performance via exposed pad. |
| Industrial temperature support | Validated operation from -40°C to +85°C enables use in base stations, motor drives, and factory automation. |
Applications
| High-Speed Digital Test Equipment | Pulse Width Modulation Control |
|---|---|
Use Scenario: Generating precisely timed stimulus pulses for jitter tolerance testing of SerDes receivers. IC Role / Device Role / Timing Role: Fixed-latency signal replicator providing five synchronized, edge-matched delay paths for multi-point sampling. Use Value: Enables simultaneous capture at 10ns intervals without FPGA-based interpolation, reducing test setup complexity and calibration overhead. | Use Scenario: Adjusting dead-time insertion between complementary gate-drive signals in half-bridge inverters. IC Role / Device Role / Timing Role: Deterministic delay element generating non-overlapping enable windows for high-side and low-side MOSFET drivers.

IC Role / Device Role / Timing Role: Tap-selectable delay node synchronizing arrival times of parallel LVCMOS inputs to a common clock domain. Use Value: Compensates for trace-length mismatches up to 50ns, enabling coherent multi-channel acquisition without custom PCB routing. | Use Scenario: Creating cascaded trigger windows in modular logic analyzers to isolate sequential state transitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-delay line applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS1100LZ-50+ | SO-8 package (5.0mm × 4.0mm); 1.5× larger footprint; identical electrical specs and delay values. | Better suited for prototyping or manual assembly; less optimal for space-constrained multilayer boards. | Select DS1100LZ-50+ when board real estate permits and reflow profile favors SO-8 thermal mass. |
| ON Semiconductor MC100EP195DG | Differential ECL inputs/outputs; 3.3V supply; 5-tap with 0.35ns resolution; ±1.5ps jitter; no industrial temp grade. | Requires level translation for single-ended systems; optimized for ultra-low-jitter telecom clocking-not general-purpose digital delay. | Choose MC100EP195DG only for ECL-domain applications demanding sub-nanosecond precision and differential signaling. |
Compared with DS1100LZ-50+, the DS1100LU-50+T&R saves PCB area and improves thermal response in dense layouts; versus MC100EP195DG, it offers simpler single-ended interfacing and guaranteed industrial temperature operation-but at lower resolution and higher jitter tolerance.

FAQ
What is the maximum input frequency supported by DS1100LU-50+T&R?
The DS1100LU-50+T&R does not specify a maximum input frequency but defines minimum input pulse width (tWI) as 20ns per the datasheet. This implies reliable operation up to approximately 25MHz (1/40ns period). Higher frequencies may degrade delay accuracy due to layout-dependent factors like decoupling and signal integrity, as noted in datasheet Note 9.
Does DS1100LU-50+T&R require external passive components for basic operation?
No, DS1100LU-50+T&R operates stand-alone with only a 0.1μF ceramic decoupling capacitor placed adjacent to the VCC pin. No pull-up/pull-down resistors, termination networks, or timing capacitors are needed-its all-silicon architecture eliminates external tuning components required by RC or crystal-based delay solutions.
How does DS1100LU-50+T&R ensure matching between rising and falling edge delays?
DS1100LU-50+T&R achieves leading- and trailing-edge accuracy through matched internal transistor sizing and symmetric delay path design. The datasheet explicitly states equal precision for both edges, with delay tolerances (±4ns for ≤40ns taps) applying identically to tPLH and tPHL measurements referenced to the 1.5V threshold point.
Can DS1100LU-50+T&R drive 74ACT logic loads directly?
Yes, DS1100LU-50+T&R can drive 74ACT loads directly. Its IOL = 8mA and IOH = -1mA exceed the 74ACT input requirements (IIL = ±1μA, IIH = ±20μA), and its VOH/VOL specifications (2.3V/0.5V at min VCC) meet 74ACT VIH/VIL thresholds. No buffer stage is needed for standard 74ACT fanout.
Is the 50ns delay of DS1100LU-50+T&R calibrated at wafer probe or final test?
The 50ns delay of DS1100LU-50+T&R is specified and tested during final electrical test at +25°C and VCC = 3.3V, with tolerance tightened to ±4ns over the full -40°C to +85°C range. Initial tolerance is ±2ns at room temperature, per Table 1 and AC Electrical Characteristics notes 1 and 3 in the DS1100L datasheet.
